Cristina,
After you change the ports on a device don't forget to do a
"Clear cache" command on the router. Your routes will still be in a
routing table for incorrect MAC ports on the Catalyst switch. These can
take an inordinate amount of time to clear out, especially if they have been
tweeked by someone. I believe the default is 30 minutes.
Good luck
Daryn

Subject: VLANs and SC0!
All,
This is a stupid question:
I have recently run into some information that has caused me to
doubt
the way a switch works.
SITUATION:
R1(E0)------(2/6)Cat5500(2/7)------(e0)R2
A catalyst 5500 (no RSM) with 2 VLAN's configured: Vlan 1, Vlan
2,and 2
routers, both routers configured for VLAN 1 with 24 bit subnet mask,
SC0 is
part of VLAN1
by default
R1 pings R2 OK
R2 pings R1 OK
Cat5500 pings both routers OK
SO far so good...
Now I moved 2/6 and 2/7 to VLAN 2, set the vtp domain name XY and
try to
ping
R1 pings R2 OK
R2 pings R1 OK
Cat5500 cannot ping the routers,neither the routers can ping the
Cat5500..
when you do a SH CDP NEIGH it sees both routers, SCO is still in
VLAN1...I
moved SC0 into VLAN 2, doesn't make a difference... DOes anybody
know why
It's much appreciated.
Thank you
Cristina
